考点三 连接从句或不定式

　　介词之后还可以接宾语从句或不定式短语，但要借助于

　　连接代词 (如：what , which, whom)

　　或连接副词 (如：how, when，where)

　　例句： I knew nothing about how he got the green card.

　　She’s pretty hesitant about which one to choose.

　　例题：

　　(1)

　　The Cubists were concerned with how----a given subject from different points of view simultaneously.

　　(A) represented

　　(B) do they represent

　　(C) to represent

　　(D) representing

　　答案：C

　　解释：介词with后面的宾语不完整, C 是不定式短语作宾语. A D都不足以和how构成宾语从句; B不应用疑问句语序, 若去掉do则是正确的

　　(2)

　　The scholarly interest in perception stems largely from questions about the sources and validity of what ----.

　　(A) it is known as human knowledge

　　(B) is known as human knowledge

　　(C) known human knowledge

　　(D) is human knowledge known

　　答案：B

　　解释：介词of的宾语残缺, B 构成宾语从句, 包含短语be known as;A多主语it; C 无法与what契合; D 语序错误

　　注意：介词后面不能够接 that 所引导的从句，除非in that连起来作为特殊的状语从句引导词，表原因

　　(3) (Exer1_21_31)

　　Soprano Julia Migenes-Johnson believes in that her Latin American background helped her interpret the role of the Spanish character Carmen in a 1984 opera film.

　　应改为：believes

　　解释：介词后面一般不能够接that 引导的从句。除非in that连起来

　　(4)

　　Hovercraft, or air-cushion vehicles, are unusual ---- travel over land and water on a layer of air .

　　(A) they

　　(B) in they

　　(C) that they

　　(D) in that they

　　答案：D

　　解释：空格前是句子的主谓语，空格后是谓语结构，空格处需要从句引导词及从句主语，只有D符合题意，in that是特殊的状语从句引导词，表原因

　　词汇：hovercraft: 水翼船, cushion: 垫子
